ABSTRACT
This paper reports the measurements of liquid+liquid, solid+liquid and solid+liquid+liquid equilibrium data of the water + 2- propanol + 1-undecanol ternary system at temperatures from 275.15 to 288.15 K. The three isothermal phase diagrams show different regions depending on temperature. At 288.15 K a liquid+liquid region is observed, however, below this temperature, solid phases appear. The experimental data have been compared with the ternary water + ethanol + 1-undecanol system at the same temperatures; some differences arise in the shapes of the different regions. Finally, by means of the distribution and selectivity coefficients, the capability of the 1-undecanol as an extractant agent in alcohol dewatering has been analyzed.
